It is a very nice tv. Had a good month at work so I bought myself a b-day present. Netflix and youtube is about the only places to watch 4k content. The Netflix app on the tv has 4k but only 1440p on the youtube app unless I use my computer. So basically I want to use youtube and a few other sites to watch 4k content. I will post some pictures tonight showing what my settings are. Right clicking and going to screen resolution only gives me a max resolution of 1920x or w/e 1080p is. No matter what settings I don't see a 3840x2160. I've played around in ccc and don't see any setting to custom display or anyway to raise the resolution. I even made sure the tv drivers were up to date. I have not called any manufactures yet as I figure they will say call Samsung or call radeon etc but that will be my next step. Is there a program that I can force a higher resolution? I will play around tonight and double check all settings and try your ideas. Thanks!!

I have the exact same problem. My card is a XFX 7790 1GB and it says on google search that its 4k compatible, I know it wont play 4k games, but would be good to get windows and youtube etc. in 4k. My TV is a Hisense LTDN42K680 which is 4K compatible.

Im getting max res of 1080p even with changing numerous options and the refresh rate down to 30hz or 24hz and no luck. Tried on both win 8.1 and win 10.

Make sure you have HDMI 2.0 on both sides (PC and TV) with a high speed HDMI cable.
I had the same issue. One of my ports were HDMI v 1.4 which carries a max of 3840x2160@29FPS / 1920x1080@60FPS. Just ask the manufacturer firmware to upgrade the HDMI port of the TV to v2.0 and make sure you're graphics card is also updated.

display/monitor 1024×768 display sizethe display/monitor uses the generic driver for display and it is 1024×768 or 800x600 but it looks very odd it should be bigger because my screen is bigger. I have a acer monitor but is there something I can download to fix the display size?
